About

Emotion is a performant, flexible CSS-in-JS library designed for writing CSS styles using JavaScript, supporting both string-based and object-based styles while delivering a strong developer experience, complete with source maps, labels, and testing utilities. It offers two powerful usage patterns; a framework-agnostic approach which requires no special configuration yet supports vendor-prefixing, nested selectors, media queries, and class composition through the CSS and CX functions; and a React-optimized variant providing advanced features like the CSS prop for direct styling (similar to the style prop but with support for nested selectors, media queries, and theming capabilities), zero-configuration server-side rendering, native theming, and compatibility with ESLint tooling. Emotion also supports styled-component-like APIs, enabling tag-based or component-based styled elements with dynamic prop-driven styling.

About

PropLine is a real-time player-props betting odds API serving 34 sports and 13 books — including Pinnacle and four exchanges (Kalshi, Polymarket, Smarkets, Matchbook) that the-odds-api and OddsJam don't carry. It is the only odds API that automatically resolves player props against actual box scores: every Over/Under outcome ships with won/lost/push/void plus the real stat value. Pricing is per request, not per credit, so player props and alternate lines don't multiply your bill the way they do on credit-metered APIs. The response schema is the-odds-api-compatible, so migrating is a base-URL change. Free tier is 1,000 requests/day with no credit card; Pro is $19/mo for 25,000/day with cross-book +EV, historical line movement and graded resolution; Streaming is $79/mo for 1M/day plus HMAC-signed webhooks. Official Python, Node, MCP and CLI SDKs.
